Abstract: A method for implementing a ring back tone, including: receiving, by a first Service Control Point, an intelligent service request triggered by a Service Switching Point, based on a call of a calling party; obtaining personal ring back tone information of a called party and/or group ring back tone information of a group which the called party belongs to; acquiring first ring back tone information according to the personal ring back tone information and/or the group ring back tone information delivering a connect message containing the first ring back tone information to the Service Switching Point the connect message being used to instruct the Service Switching Point to connect the call to an Advanced Intelligent Peripheral for playing the ring back tone to the calling party according to the first ring back tone information.

Abstract: A method for invoking the service in the intelligent network includes realizing the communication between the different service control points in the intelligent network and providing various intelligent service to the users by the cooperation between the communicating service control points according to the service request information of the user. The method for invoking the service in the intelligent network of the present invention enables the process of invoking the intelligent service to have better application and extensibility. The process of various service invoking needn't limit to the service control point of the same manufacture.
